Which error message (if any) do you receive when you try to access these websites?

Have you enable any restriction for cockies?

Are you using a firewall or some ad blocker like Proxomitron, AdHunter, etc.?

thanks for your question.  the message displayed was  that the page
cannot be displayed. i don't know about cookies, but i have deleted
off-line files under internet options., history , and stll not able to
log onto the website. no. i have no firewall etc.yes,adblockers seems
to be working in my pc. the  point is, other computers can access the
sites, why not mine? mine can access other sites anyway. as regards
the new browsers, etc, i 'll try later.  thanks anyway.

you can check for security settings on your browser. You can to try to
download other   browsers and verify with them.

Firstly, the presence or absence of "www." is not important. As far as
the internet is concerned, its just a name, however some software
makes its own rules up (e.g. the Start Menu -> Run dialog box - you
can type raw www.site.name into here and it 'guesses' to launch ie,
but site.name alone must be http://site.name or it thinks its a
program to run :).

Just stick to typing in http://site.name and all should be fine on that side.

Internet Explorer is terrible at reporting any form of error
connecting and almost always returns page can not be displayed if
theres any issue at all.  Something like Mozilla (www.mozilla.org) may
produce a useful error.

If you can glimpse the messages that flash on the status bar before
the error this can help, however they're often very fast.

An easy way (!) to test the connection to the web server is to open a
command prompt (Start Menu -> Run, type 'cmd' in and press enter for
win2k/xp), and in the box that appears type "telnet webservername 80"
- for example "telnet www.microsoft.com 80".  If it reports an error
then you have a connection problem to the target server, if it clears
the screen then its connected OK.  If you type junk into this now and
press enter a few times you should get a HTML error message about the
request being invalid (note you cant see what you type - type "GET /
HTTP/1.0" and press enter twice to actually get an index page)

If the telnet fails, list the error.  If the telnet succeeds then
another possibility is ad blocking software - this can be detected by
a crafty coder, try turning it off.
